Dr. MILAN VUKOVIC who passed away recently, was one
of WRP's highly respected authors. In his many year of practice
he had designed, tested, analyzed, and evaluated pumping tests
and production pumping in almost 1000 wells. He was the author
of more than 90 scientific and technical publications, three
books and three monographs. Of particular significance was his
contribution to the construction of the largest hydraulic engineering
facility in Yugoslavia, the Iron Gates Hydro Power Plant, as
well as to the development of a large number of groundwater aquifers.

Dr. Vukovic was Professor of Hydraulics and Groundwater Dynamics
at the University of Belgrade, Department of Mining and Geology.

ANDJELKO SORO, is Chief Engineer of the Groundwater
Hydraulics Department at the Water Resources Institute "Jaroslave
Cerni" in Belgrade, Yugoslavia.

He has worked for more than 20 years in the field of scientific
research and applied investigation of groundwater problems. His
practice includes numerous research projects, particularly those
related to construction and maintenance of facilities for conservation
of the artificial lake riparian area of the larges Yugoslav hydropower
plant, the Iron Gates. A major portion of his work included research,
design and optimization of groundwater development, primarily
in alluvions of large rivers (Sava and Danube).

A special part of Mr. Soro's expertise was dedicated to developing
of mineral resource deposits from the viewpoint of drainage conditions
and the open pit protection.

Mr. Soro is the author of more than 30 publications and co-author
of three books in the field of groundwater hydraulics.
